clm6 cannot support more then 15 users

William Xu (811) | asked Aug 06 '15, 8:21 p.m.
I used clm6.0 with ifix01 in production environment, the WAS and DB2 10.1WAS10.1 used also.
For configuration, I used all components in one application server, DB2 in another server, LDAP also.
I can use it normally with less 15 users, but system will always no response if users up to about 20.

any ideas you suggest for me to address this issue?

I only think of CLM licensing. What type of license are you using? 

We need more about your configuration in order to research.
How do you know "no response if users up to about 20"? Which application do you use RTC, DNG, RQM?
Can you give us the outout of db2licm -l against DB2 10.1?
What do you mean by "WAS and DB2 10.1WAS10.1"? Do you have 2 WAS?

Hi William,
This is something for the support. Please gather Mustgather for performance and hang (especially wait tool) and open PMR for the support. Alternatively you can provide the output from WAIT Tool if you don't want to open PMR yet.

We run CLM instances with several thousand users - there are tens of thousands users looking at the RTC project area here on If you can't provide a better error description/what you see in the log files and what the symptoms are, it is hard to help.

What I can think of is that your systems don't have enough resources available. Also see for suggested topologies to scale the system. I would however assume that you should be able to host more than 20 users on one box with the app server and the applications and one box as database backend.
